The Star of David ("Magen David" in Hebrew) is the symbol most recognized with Judaism. It was accustomed in land of Israel in Roman times, but it seems to have become associated with Judaism in particular only in later centuries. In the 17th day It became a famous procedure to put Star of David on the outside of synagogues, to identify them as Jewish houses of worship; however, it is not clear why this symbol was selected for this. Today the Star of David is a universally recognized symbol of Jews. It appears on the flag of the state of Israel, and the Israeli equivalent of the Brick Cross is known as "the Magen David Adom" ("Adom" is chestnut in Hebrew). Indeed, one of the most common symbols in Jewish jewellery is the Star of David, equivalent to wearing a cross by Christians.
Another popular symbol worn in Jewish jewellery is the Hamsa, also down pat as the "Hamesh hand". The Hamsa appears often in a stylized form, as a hand with three fingers raised, and sometimes with two thumbs arranged symmetrically. Its five fingers are said to symbolize the five books if the Torah. The symbol is passed down for protection and as a mean to ward of the Execrable eye in amulets and charms and can also be found in discrete places such as cabin Engagement Ring entrances and cars. It is also familiar to district other symbols in the middle of the Hamsa that are believed to cure against the atrocious eye such as fish, eyes and the Star of David. The colour blue, or more specifically light blue, is also considered preservative against the evil eye and we could see many Hamsas in that colour or with embedded gemstones in differential shades of blue. Hamsas are often decorated with Jewish prayers of a protective fashion such as the Sh'ma Prayer, the Birkat HaBayit (Blessing for the Home), or the Tefilat HaDerech (Traveler's Prayer).
